TIE-PLATE FOB RAILW'AYS.

Specification of Letters Patent.

Patented July as, rare.

Application filed October 19, 1907. Serial No. 398,238.

T 0 all whom it may concern: Be it known that I, \VILLIAM L. DE MEK, a. citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tie-Plates for Railways, of which the following is a specification.

This invention relates to tie-plates adapted to be secured to the ties of a railway, to protect the ties and form a support for the track-rails The principal object of the invention is to provide a simple, economical and etlicient tie;plate for railways.

Further objects are to provide a tie-plate of minimum weight and maximum effectual strength, reinforced at the point which comes beneath the outer edge of the rail when in position, by a transverse depend, ing shoulder or relatively thick portion and having on the under side of the plate extciuling below the level of the transverse reinforce and converging at the longitudinal central portion of the plate from which they extend obliquely in different directions so as to form wedge-like depending rib portions having their points toward one end of the plateand having unobstructed spaces between separate outer end portions of such ribs, whereby the plate is strengthened and stiffened both longitudinally and I transversely and a wedging effect is obtained which tends to increase the rigidity of the connection between the plate and tie and causes the plate to adhere more tightly and fit more snugly to the tie as it is wedged in by the lateral strains upon the rail supported thereby.

Other and further objects of the invention will appear from an examination of the drawings and the following. description and claims.

The invention consists in the features, combinations and details of construction hereinafter described and claimed.

In the accompanying drawings Figure 1 is a. plan view of a plate constructed in accordance with my improvements; Fig. 2, a side elevation of the same; Fig. 3, a transverse sectional view taken on line 3 of Fig. 1, looking in the direction of the arrow; Fig. 4, a bottom plan view of "the plate; and Fig.5, a bottom plan view of a segmental portion of obliquely extending retaining ribs.

' body 1 a plate showing a. modified arrangement of the bottom retaining ribs.

in constructing a tie-plate'in accordance with my improvei-nents I provide a main portion a formed perferably of rolled metal, and having on its upper side a. transverse rail-engaging or rail retaining shoulder 6. Perforations c extend through the rail-retaining shoulder and body portion of the plate in position to admit spikes for engaging the outer edge of a rail (Z to be held in position upon and supported by the plate,

and perforations e are provided at suitable intervals near the opposite or inner end of the plate through which they extend in position to admit spikes for engaging and holding in place the inner edge of the rail. Transverse grooves f extend across the upper face of the plate in parallel relation to the upper rail retaining shoulder, and upper face portions gon opposite sides of these grooves form the rail, supporting surface portions of the plate. ,011 the bottom side of the plate, depending retaining ribs h are n'ovided which are preferably so disposer as to leave flat or non-ribbed margii'ia-l portions along two edges of the plate. The flat bottomed overhang thus formed on opposite sides of the plate serves to exclude moisture from entering the creascs in the tie to some extent and protects the tie, and together with the flat bottom surface portions of the plate which are between the ribs forms the main load supporting bottom surface U. the plate. ,The substantially fiat bottom surface portion of the platethus formed by the portions 2' between the de pending ribs and the marginal portions j are substantially continuous and connected. A relatively thick or reinforced transverse portion in extendsacross the under side of the plate beneath the upper rail-engaging shoulder and in such position that it is beneath the outer edge of the rail when. in position thereon. This depending transverse shoulder or reinforce extends below the level of the main flat bottom surface portion of the plate and the upper surface of the portion p which is outside of the upper rail engaging shoulder is depressed so that'it is below the level of the surface portions 9 a distance correspoinling with the depression of the bottom face of the reinforce l1 below the surfaces 2' and j. p

The bottom retaining and strengthening ribs h extend below the level of the bottom face of the reinforce 7c and'they also extend pbhquely across saidreinforce and obliquely 1n dlffercnt' dlrections from the same and from the longitudinal central portion of the plate where they converge. They are preferablyin parallel relation and form Wedge- I like rib portions. The wedges thus fornied are separate and the points all extend pref- .10

erably in the same direction and toward one 'of; the ends of theplate, preferably the outer end, The ribs are also V,-shaped in crosssection so that they. form wedges in a ver-- tical plane as well as in a horizontal plane.

' entirely separate so that the surface The widest portions of the wedges, or in other words, the outer ends of the ribs are por tions of thetie engaged by theflat surface By arranging the depending ribs portions of the plate between the ribs are neath the overhang or margins This prenot entirely separated from the portion beby ha'ving the outer ends 0 form thenex-t adjacent wedtge portions, and

the converging "ribi ortions or wedges on opposite sides of [the ongitud'inal center of the plate, so that eaph' a rlof converging ribs forms a wedge .:,a 1 1i1 a lofv the wedges overlap and formsep a'r'ate wed'ging surfaces, all ofthe wedges .gfthe seriesthus formed converging toward and the same ed' 'e of the plat'e,1t will be seenthatithestrengt of the plate both lonjgiitudinallyiand transversely 1s ii1ereased b from itsv seat.

t e..seme-,1'ibs,which serve t o provide a hesion'or'to retain the plate in position and resist the side thrusts upon'the railto be. supported thereby. The wedge-like de endare adapted to be wedged tightly into securing engagement with the tie it by the side thrusts ing ribs or projections, thus forme upon the rail 0 which would otherwise have a tendency to loosen the plate or force it surfaces of the wedges are both at the same angle with relation to the base or widest.

part of the wedge formed thereby, the outer ends ofveach pair of ribs being in a line 7 parallel with the transverse depending shoulder kalready described. This shoulder is substantially flaton its under side and exj tends from a point inside of the upper shoulder outward to or in the direction of -lel with the uppersurface portion pwhich is depressed,as shown, so as to be below the level of the upper rail bearing surface tions'g which are between the upper shoulder and the inner end of the plate. In other The converging outer side words there is an oifsetin the plate, the upper face which is outsidefof the upper shoulder bein preferably parallel" with, the surfaces 9 w ich engage and support the the outer surface p. The bottom main surface portion of the de ending shoulder or reinforce la is an equal distance below the level of the main bottom surface portions e, and the bottom edgesofthe ribs It are below the level of both the surfacesi and the bottom surface of the transverse reinforce or shoulder It. This depending shoulder considered independently of the depending ribs, isof less depth than the ribs and provides .fiat bottom surface portions which are adapted to compress the fibers of the tie ben'eaththe outer edge of the rail without cutting or mutilating them, and. it serves not only to 'stren hen the plate but to elevate the outer e ge of the rail .as desired and efi'ectually. resist the side thrusts upon .the rail. It'also cooperates with the depending oblique ribs in reventing the longitudinal movement of the plate. .Its inner side face being inclined upward and toward the inner endof the plate, it serves to draw the Wedge-like ribs more tightly into engagement or 'wedging'contact with the fibers .of the tie as it is forced down-into position. The late thus formed is adapted to be a I rolled y means of cylindrical rolls. A- multiplicity of the plates can be rolledin either direction'either transverselyor longitudinally of the platesfand from a, single strip of metal, the shoulders, ribs, reinforce and grooves being formed by a single rolling operation.
